Notification handling: Rejected

[ibu58]

Hello

I am a beginner of OTRS.
And English is not my native language. Please forgive me for typing errors.
I have a question about the use of OTRS.
It might be a FAQ but I could not find a way.
I have created some workflow processes
It is possible to notify the approver by updating the ticket queue, but if you refuse, I would like to notify the requester by adding an article.
How are you doing?
I think it would be better if you remember in the dynamic field
I do not know how.
How do I store the requester's queue in advance?

Thank you in advance
